php - PHP等同于.NET / Java的toString（）(PHP equivalent of .NET/Java's toString())

Question

How do I convert the value of a PHP variable to string?

(如何将PHP变量的值转换为字符串？)

I was looking for something better than concatenating with an empty string:

(我在寻找比连接空字符串更好的东西：)

$myText = $myVar . '';

Like the ToString() method in Java or .NET.

(类似于Java或.NET中的ToString()方法。)

You can use the casting operators :

(您可以使用强制转换运算符 ：)

$myText = (string)$myVar;

There are more details for string casting and conversion in the Strings section of the PHP manual, including special handling for booleans and nulls.

(PHP手册的“ 字符串”部分提供了有关字符串转换和转换的更多详细信息，包括对布尔值和null的特殊处理。)
